Summarizing various sources, ransomware is a type of malware virus that attacks devices with an encryption system. As a result, if the system is infected with the virus, the data cannot be read by the computer or laptop that is being used. This virus can be removed as long as there is an encryption code.

"On behalf of Bank Syariah Indonesia, we apologize for the inconvenience to customers due to problems accessing BSI services on May 8, 2023," he said.
